I had purchased some to waterproof my boards. I also purchased a light to view the product when applied (can't recall what type - black light maybe?).
When I opened up my gear to apply the coating, wouldn't you know it, they were already coated with conformal coating! My ego's had it all over the circuit boards, and my Empire Z2 had it near the microchips, etc.
Honestly, even if you are 100% ready to get gnarly in the mud, you may have trouble finding players to accompany you out there.
